I guess this is a bit old but it's super cool litterally! The man himself macci
wrote about his dual cascade cooling! Lots of pic's and I'm sure you'll love
checking this thing out!
Four (4) compressors cooling one PC! Yes its big, yes its heavy, yes its
loud and YES IT DOES GET YOUR CPU AND GPU COLD - VERY COLD - EVEN DAMN COLD!
Is -100C cold enough for you?
